Entering DFU mode from Apple logo bootloop
I have an iPhone I am trying to get into DFU mode that constantly boot loops when it is turned on. I am using 3U tools but cannot get the phone to stop looping and enter recovery or DFU mode. It also red screens regardless of whether the proximity sensor cable is connected or not.
Maybe it has a damaged NAND?
Or is it just something I'm doing incorrectly when trying to get it to enter DFU mode?
I have managed to get an iPhone 4s to enter DFU mode using the same technique.
What is the best technique I should be using? There seems to be a variation on how long to hold each button when searching online.
